Enum PushError 

pub enum PushError {
    Full(SignalItem),
    Discontinuity {
        expected: Tick,
        found: Tick,
    },
    Channels {
        expected: u8,
        found: u8,
    },
    Ended,
    Stalled {
        waiting: Vec<(String, Wait)>,
    },
    UnknownSource(usize),
}

Why a source did not take an item.

Variants

Full(SignalItem)

The source holds as many blocks as it may; run the pipeline and read its outputs, then push the item again. If the samples cannot wait, push a gap for them instead.

Discontinuity

The item does not follow the previous one; lost samples must be announced as a gap.

Fields

expected: Tick

The tick the source expects next.

found: Tick

The tick the item starts at.

Channels

The block has another channel count than the source.

Fields

expected: u8

The source’s channels.

found: u8

The block’s channels.

Ended

The source has ended.

Stalled

The source is full, the last run moved nothing and no exposed output has anything to read: the pipeline can make no progress, however it is driven. A node that waits on one input while another holds the source’s queue does this; see design.md §4.

Fields

waiting: Vec<(String, Wait)>

What each unfinished node waited for when the last run ended.

UnknownSource(usize)

No such source.

Trait Implementations

impl Debug for PushError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PushError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PushError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
